When a fault occurs, an audible alarm is triggered and a message is displayed on the HMI(s). The Audible
Alarm can be silenced by pushing the Mute button that appears on the screen.
At any point in time, the control can be changed from Manual to Auto mode and vice versa. This is
achieved by simultaneously pressing both top buttons and holding them for 1 second. When this occurs,
the screen will look similar to the image to the right.
To change operating modes:
1. Press and hold the top 2 buttons for 1 second. This will bring up the configuration screen.
2. The mode should be highlighted. If the mode is not highlighted, use the up and down buttons to
navigate to mode until it is highlighted.
3. Once the mode is highlighted, press the ENTER button.
4. Use the UP and DOWN buttons to select the desired mode. For initial start-up, select MANUAL mode.
Once the desired mode is selected, press ENTER.
5. This will bring back the main Configuration Screen. If the desired mode is correct, press the DISPLAY
button to go into that mode of operation.
